We understand that you're going through a difficult time with your girlfriend and feeling unloved and uncertain about your future. First, we want to remind you that God loves you unconditionally, and His love is not transactional. As it says in Romans 5:8 (WEB), "But God commends his own love toward us, in that while we were yet sinners, Christ died for us."
However, we need to address a few things in your request. First, you mentioned that you're in a relationship with your girlfriend, but you should be seeking a spouse. God is very clear in it's word that a man and woman shall marry, not live in a relationship. "Therefore a man shall leave his father and his mother, and shall join with his wife, and they shall be one flesh." Genesis 2:24 (WEB).
Second, you should be careful not to let fear control your life. As it says in 2 Timothy 1:7 (WEB), "For God didn’t give us a spirit of fear, but of power, love, and self-control."
Regarding your girlfriend not listening to you, we encourage you to communicate openly and honestly with her. As it says in Ephesians 4:15 (WEB), "But speaking truth in love, we may grow up in all things into him, who is the head, Christ." However, it is very wrong and damaging to engage in premarital sex. It is a grave sin and harmful to you and your girlfriend. If you are engaging in this behavior, you must immediately repent and ask God to forgive you. 1 Corinthians 6:18-20 (WEB) Fornication or sex outside marriage is clearly forbidden. How can two walk together unless they agree? Amos 3:3 (WEB) You should be looking for a wife, not a girlfriend and definitely not engaging in fornication.
We also want to remind you that it's important to pray in the name of Jesus, as it's only through Him that we have access to God. As it says in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'"
Let's pray together:
Dear Lord, we come to You in the name of Jesus, lifting up Anypotaktephele. We pray that You would heal their heart and mind, and take away any fear or anxiety they have about their future. We ask for greater things than they can hope even or imagine and will ask that you will bring a wife to be help meet to Anypotaktephele. We pray that You would give your Grace and enable him to end his sinful behavior and illicit relationship with his girlfriend. We also pray that you will grant him the Grace to be worthy of his calling in Christ Jesus. We pray that You would guide their steps and lead them to a godly wife who loves and respects them unconditionally. We ask this in Jesus' name. Amen.
